DATUM® Integrated Compression System

Building on the successful experience of the DATUM® line of compressors, Dresser-Rand developed a new compression concept – the DATUM Integrated Compression System (ICS). The compression system is engineered with centrifugal separator technology incorporated on the compressor rotor to provide an efficient, compact solution to compression system design. The DATUM ICS is designed for onshore, offshore, and subsea applications.

Versatile and Efficient
Features of the DATUM ICS system include the high-efficiency DATUM centrifugal compressor technology; Dresser-Rand’s proprietary centrifugal separation technology; a high-speed, close-coupled, gas-cooled motor; magnetic bearing rotor system; dedicated unit controls; process coolers, valves, instrumentation, and interconnecting piping – all packaged in a compact module design. The DATUM ICS is a complete compression system that can be applied to all markets – upstream, midstream, and downstream – with a small footprint, reduced weight, and at the lowest total cost. Each DATUM ICS integrated compression system is factory-tested and provided as a fully assembled module. As a result, installation and start-up times are reduced, and production could begin sooner than otherwise possible with traditional modules.

Competitive Performance
By incorporating Dresser-Rand’s proprietary centrifugal separation technology inside the compressor case, the DATUM ICS system efficiently separates liquid from the gas stream. This integrated approach makes the DATUM ICS system competitive with the overall performance of traditional systems when the suction scrubber and inlet piping losses are taken into account.

Advanced Technology
The DATUM ICS system provides an efficient and compact method of gas-liquid separation that uses centrifugal forces to separate gas, oil, and water from the flow. The separation process protects the compression flow-path from potential damage by removing free liquids from the gas stream which can cause subsequent fouling during the compression process. Oil and gas operators benefit from the overall size reduction of production facilities, platforms, and subsea modules because of the small footprint of the DATUM ICS compression system.

Uniquely Suited for Subsea
The DATUM ICS separator / compression system product development follows industry standards supporting technology qualification programs which readies the product for intended applications. The same features that provide value for topside applications are enhanced in a subsea environment. The centrifugal separator provides the motor cooling system with cleaner and dryer gas when compared to other solutions employing process gas as a cooling medium. With higher system reliability extending intervention intervals, associated operating costs are reduced.
